The warning you're encountering during the build process of Apache AGE on MacOS is related to an unused variable cypher_yynerrs in the generated cypher_gram.c file. This warning doesn't necessarily indicate an error, but it's informing you that the variable is defined but not used within the code. To resolve this warning, you can either remove the unused variable or suppress the warning altogether. Here's how you can address it: Remove the Unused Variable: You can edit the cypher_gram.c file and remove the declaration of cypher_yynerrs if it's not needed for any future use. However, be cautious when modifying generated code as it might affect the functionality of the parser. Suppress the Warning: If you prefer not to modify the generated code, you can suppress the warning using compiler directives. For example, if you're using GCC or Clang, you can use the -Wno-unused-but-set-variable flag to suppress this specific warning. Add this flag to your CFLAGS when configuring or compiling AGE. ./configure CFLAGS="-Og -Wno-unused-but-set-variable" --enable-tap-tests --enable-debug --enable-cassert --prefix=/tmp/pgsql Adding this flag instructs the compiler to ignore warnings about unused but set variables, which includes cypher_yynerrs in this case. By removing the warning or suppressing it, you should be able to build Apache AGE without encountering this specific issue. However, always ensure that the changes made do not introduce unintended consequences to the functionality or stability of the codebase. -- This is an automated message from the Apache Git Service.
